Mining mobile type power-supply-free water cutter

Abstract

The invention discloses a mining mobile type power-supply-free water cutter. The mining mobile type power-supply-free water cutter consists of components including a water cutter spray nozzle, a cutter bar, a high-pressure rubber tube, a sand amount regulating handle, a base, a supporting leg, a mixing valve, a foot wheel, a mixing tank, an end cover, a pressure relief valve, a pushing-pulling handle, a one-way valve, an unloading overflow valve, a pressure regulating hand wheel, a pressure flow rate regulating valve, a pressure flow rate regulating handle wheel, a clear water tank, a clear water tank cover, a high-pressure filter, a filter, a booster pump, a shaft coupler, a safety valve, a hydraulic motor, a motor liquid inlet, a motor liquid return hole, a motor liquid return joint, a booster chassis, and the like. The liquid passes through the high-pressure filter through the regulating valve to enter the hydraulic motor for rotating the hydraulic motor, the hydraulic motor drives the booster pump to rotate to generate high-pressure water; the high-pressure water enters the mixing valve through the unloading valve; the mixing valve is used for mixing the high-pressure water with a grinding material in proportion; mixed water is conveyed to the cutter bar through the high-pressure tube; the speed of the water cutter spray nozzle is instantly accelerated to 340m / min so as to generate great dynamic energy to cut a performing element.

Description

technical field [0001] The invention relates to a mine-used mobile water cutting machine without power supply, specifically a kind of water cutting machine for safe production in a high gas environment in a coal mine, ensuring that no sparks are generated, no power supply is used to drive, and an emulsion motor is used to drive a booster pump so that the water reaches A certain pressure; the high-pressure water enters the mixing valve through the unloading overflow valve. After the mixing valve mixes the high-pressure water and the abrasive in the mixing tank in proportion, the abrasive mixed water is delivered to the cutter bar through the high-pressure rubber hose, and the abrasive mixed water is accelerated instantly through the water jet nozzle. To the speed of sound, a device that generates huge kinetic energy to cut the actuator.

AI Technical Summary

Problems solved by technology

[0002] At present, the coal mining work in the underground high gas environment of the coal mine is faced with the cutting of metal objects. If traditional plasma cutting, acetylene gas cutting, hacksaw blade cutting, etc. are used, flames and sparks will be generated, causing underground gas explosions; in order to ensure the safety of high gas underground In production, the coal mining face avoids the use of electrical appliances as much as possible, and uses emulsion as the power source; drives the emulsion motor as power, and replaces the electric motor with power as power; It can also drive the booster pump to make the hydraulic system reach a certain pressure, and the abrasive mixed water is accelerated to the speed of sound through the water jet nozzle instantly, and a device that generates huge kinetic energy to cut the actuator can solve this problem.
